Identification of Tsunami Deposits in the Geologic Record

Sediments deposited by tsunamis have been studied in the past as records of catastrophic events. The earthquake and tsunami that struck the Indian Ocean region on Boxing Day 2004 and claimed around 200,000 lives highlighted the need to study the sedimentary record of past tsunamis to help with planning disaster mitigation measures in coastal areas threatened by tsunamis. To help with the description and assessment of paleo-tsunami records the USGS has published an Open-File Report

Peters, Robert, and Jaffe, Bruce E. (2010): Identification of tsunami deposits in the geologic record; developing criteria using recent tsunami deposits. U.S. Geological Survey Open-File Report 2010-1239, 39 p. http://pubs.usgs.gov/of/2010/1239/.

This reminds me that I have not heard for a while about the "Mother of all Tsunamis" triggered by the Chicxulub impact. The field seems to have quieted down after 2008.

Geobulletin now has a new 'weekly review' page, a summary of the Geoblogosphere's weekly blogging activity.
The 'weekly review' page shows the top 10 most active and most visited blogs. It gives a rough overview on the topics treated in geoblogs by listing the most frequently used keywords and the places and stratigraphic ages most often used in blog posts. Further, it shows a list of the Geoblogosphere's top 10 blog posts based on the visits tracked at geobulletin.org.

Chinese Google Maps alternative provides geological data

Just found at Asia News:

China has launched its official online mapping service, Map World, as Google Inc has yet to apply for a Web mapping license in the country.
The State Bureau of Surveying and Mapping (SBSM) officially unveiled the free online map service on Thursday (October 21). The service will provide "comprehensive geological data", said Xu Deming, director of the SBSM, at the launch ceremony.

The tool which can be found here unfortunately is in Chinese.. so I was not able to find this feature.. Maybe one of you have been more successful?
